Distribution Free Hypothesis Testing: One Sample Sign Test Example (C)

Twenty-one students at a large college undergo a standard test to measure their reaction time to a particular stimulus. The median reaction time in the population generally is believed to be 7.8seconds The reaction times for this sample are: 6.6  3.6  2.1  13.2  5.4  11.6  1.6 7.2  7.8  3.8  6.0  14.2  3.0  15.2 4.7  2.8  7.5  6.9  21.6  6.7  4.3 Use a sign test to test, at the 5% significance level, the hypothesis that the median reaction time is 7.8 seconds Recorded with https://screencast-o-matic.com
